The invention relates to radioreceiving sets arranged concentrically therewith and thereby providinga harmonious inconspicuous relation to the appearance of the casing.

. It is also an object to provide a radio set of the foregoing character in which a loud speaker. is located in the upper part of the casing with a grille or apertured cover thereover constituting the topof the casing and supporting the shade bracket of a lamp.

. Other objects and advantages will become apparent from the following description taken. in connection with the accompanying drawing, in

which:

, Figure 1- is an elevational view on a reduced scale of a combined lamp and radio receiving set embodying the features of the invention.

Fig. 2 is a vertical sectional view of the pedestal of the device shown in'Fig. 1.

The preferred embodiment of the invention comprises generally an upstanding casing enclosingradio apparatus and mounted in spaced relation above a base. The radio apparatus includes, among other parts, a loudspeaker mounted in the top of the casing and a rotatably adjustable element mounted in the 'lower part thereof. To adjust said element, a rotatable controlmember is located in the space between the casing and the base and conforms in appearance thereto.

The control element is so fashioned as to permit 7 the casing to be rigidly supported by the base. V .In the present instance, the casing and base constitute the pedestal-of a -lamp,and to support the electric sockets and shade of the lamp, 2. cap

is provided for the upper end of the casing, which is eper ured to p rm t egress, of the sound from or arrow 25 on the base l2.

the loud speaker; Extending from the cap is a bracket for thesockets and shade.

As shown in the drawing, the casing is in the form of a vertically extending cylindrical sleeve I 10 of material having a decorative appearance,

which may be varied to suit different tastes in the matter of decoration. The sleeve I0 is carried by an internal frame structure, indicated generally at' II, and is positioned in spaced relation above a base 12. The latter is preferably hollow and carries means for supporting the casing comprising a pair of threaded members I3 holding the casing-in suitably spaced relation by spacers'llL.

Withinthe casing is the radio apparatus includingan adjustable element which, in the present instance, is the rotatable element of a variable condenser I5 mounted inthe lower part of the casing. The rotatable element has a shaft l6 extending below the casing; v

To adjust said element, a control member is mounted in the space provided bythe spacers l4 between the casingandthe base l2, andin its preferred form isa disk-shaped member 20 attached to the shaft; l6 as by bushing 2| and lock nut 22. :The control member 20 is rotated to adjust the'condenser l 5 and is of sufi'icient diameter to extend at least. to the periphery of the casingv l0 so that it may bemanually operated. In the form illustrated, the, member 20 has a beveled periphery 23 extending beyond the periphery of the casing and-having suitable graduations 24 thereon to cooperate with a fixed point In appearance, the beveled periphery 23 harmonizes with the casing as to itsfunction Since thecasing 1| lisfixedly .supported by the threaded members :I3 andthe'control member 20 rotates,,the=latter isuconstructed. to permit of such rotation with the threadedmembers l3 extending through the controlm'ember. To this end, the control member 20, is provided with a pair of arcuate slots 26- through which the threaded'supporting members 13 extend. The range of adjustment for the'condenser I5 is pref erably approximately so that the slots 26 are given such length, and the. supporting members are placed at different radial distances from the axis of rotationto permit the slots to be given such length without opening into each other. I h H The radio apparatus receives power through an electrical cord 21 enteringthe hollow base l2 through an1aperture 28. To-conduct the cord 21 structure II comprises, inthe present instance a pair of strips 30 preferably made of sheet metal with their ends bent at right angles to provide attachment lugs. Connecting the strips3q are transverse parts placed at whatever heights as are desired to support the various pieces of radio apparatus. In the preferred embodiment, .a transverse part comprising a strip or plate 3| connects the bottom ends, of the 'vertical strips 30. If desired; one :of the threaded supporting members l3 may be used to attach one of the vertical strips 30 to thetransverse plate 3! at one end-and a bolt and nut 32 used to attach the other end of the transverse plate 3| to the other vertical strip 30. g r

The preferred embodiment also includes a transverse plate 33, in the form of a disk, intermediate the upper and lower ends of the strips 30, to support tube sockets 34 of the desired number and tubes 35. To simplify manufacture, each vertical strip 30 is made of two parts in end-to-end relation and secured together by bolts 36 which also secured the transverse. 'plate 33 at that height. A condenser 31 as well as resistors and wire connections for the tubes may be carried on the lower face of the plate 33.

The upper end of the casing is utilized for the loud speaker mounted concentrically with the casing and comprising a pot), a cone 4! and a cone support 42. .Preferably the pot 40 is supported by a rod 43 threaded into the transverse plate 33 while the periphery of. the cone support 42 is carried on theupper ends of thevertical frame strips 30 and is secured thereto as by bolts 44. To provide rigidity, a reinforcing ring 45 is placed over the periphery of the cone 4| and is secured by the bolts 44. Chokes 49 may be carried by the cone support 42. To close the upper end of the casing, a cap 46 of suitable. external appearance and configuration and provided with apertures to permit the egress of sound is also secured on the upper endof the casing by the bolts 44. I a

The sleeve I ll of the casing is preferably secured in place at both ends by rings clamped in place by the frame bolts and preferably having flanges 48 telescoping over therespective ends of the sleeve 10. The upper end of the sleeve I 0 may have a-plurality of apertures 51 to provide ventilation for thecasing.

As mentioned above, the: casing and base l2 are of such form that they are adapted for use as a decorative article of house-furnishing such as a lamp pedestal or base, To this end a bracket comprising a pipe is' s'upported by the cap '46 and constitutes asupport for suitable lamp sockets 5| and for a shade 52. For wiring, the electrical cord 2-l supplying current to the radio setmay be'tapped inside of the casing as by branch wires 52, and the latter carried up within thecasingto-a notch" 53 in the reinforcing ring 45 and thence into the pipe 50. r

A combined switch-andrheostat '54, constituting part of the radio apparatus, may also be mounted in the casing, preferably in the lower part thereof, and supported by the ring 41, with its adjusting shaft 55 extending through the wall of the casing to receive an external knob 56.

In operation, electrical current is carried to the radio set by the cord 21' and is controlled by the combined switch and rheostat 54. To adjust the condenser 15, the control member 20 may be rotated by placing the fingers on the external beveled surface 23 thereof. The arcuate slots 26 in the control member permit rotation there- 'of without interference by the fixed casing supporting members l3.

The radio apparatus is all compactly enclosed in acasing of relatively small size and of such form and appearance that is remarkably adapted to serve as the base or pedestal of a lamp. Theexternal portion of the control member 20 harmonizes with the adjoining casing and base 12 so that it is relatively inconspicuous, while the cap 46 serves to permit egress of sound, from the loud speaker and has an appearance artistically conforming to the casing in its function as a lamp pedestal.
